Could we get some more information on the matter?
Over the past years there have been numerous people online which have claimed that Hetzner closes accounts without giving a reason. I'm sure most of those claims intentionally omit some details to make it look like they didn't infringe the T&C.
However as a Hetzner customer (a small one, to be fair), I'd still like to know that those complaints are baseless, and that I can still trust your company.
This is the relevant part from their T&C:
2.7. Furthermore, we reserve the right to terminate the contractual relationship without notice for good cause.
